Drug half-lifes

Below is a list of drugs and how long they stay in your body for. The most effective and accurate test for drugs is a hair test as it can test positive for cocaine for up to 3 months after taking it. Hardly anyone does a hair test though. The most common test is a urine test, then a blood test.

Note: Although some tests test for the drug itself, some test for the associated chemicals which are mixed with the drug. Also certain foods help to get rid of drug traces faster.
